MOSCOW, March 28 (RAPSI) – The Zavodsky Court of Kemerovo on Wednesday detained Nadezhda Suddenok, a renter of the city’s Zimnyaya Vishnya (“Winter Cherry”) mall which became a site of the nation-wide tragedy after a fire took lives of 64 persons, until May 25, the press-service of the court told RAPSI.

The court is also reviewing a motion to detain four other defendants: a renter of a place where the fire allegedly began, a CEO and an employee in an organization maintaining the fire alarm and a guard who allegedly turned off the emergency notification system when he received a fire signal.

The fire in the mall occurred on March 25. Investigators reported that 64 persons including children were killed in the accident. A criminal case has been launched over involuntary manslaughter, violation of fire safety regulations that left more than two persons dead and provisions of services that don’t meet safety requirements.

According to the Investigative Committee Chairman Alexander Bastrykin, the two main versions of the tragedy are an electrical short circuit and burning. Investigators noted that fire alarm was inactive since March 19.

Russian President Vladimir Putin declared March 28 a national day of mourning.
